Abstract

The invention provides a heavy metal detection method. The method in the invention comprises the steps of: first, preparing a heavy metal dithizone solution and using a digital camera to collect colors in three different shooting conditions; then, using photoshop software to collect data on pictures of different colors; and finally, making a spectral analysis.

Description

technical field [0001] The invention relates to a method for detecting heavy metals, in particular to a simple method for measuring the concentration of heavy metals. Background technique [0002] Heavy metals have many different definitions. Most of the heavy metals mentioned in daily life are based on the definition in the field of environmental pollution. Metals or metalloid elements with obvious toxicity to organisms are regarded as heavy metals. Since metalloid arsenic has obvious toxicity to organisms, arsenic will also be regarded as listed in heavy metals. In addition to the above definitions, a common definition in the scientific community is a metal with a density greater than 5, most of which are heavy metals. The chemical properties of heavy metals are generally relatively stable. [0003] In the field of environmental pollution, heavy metals mainly refer to metal elements or metalloid elements that are obviously toxic to organisms, such as mercury, cadmium, l...
